A2_8 Sunshades for the Earth

Abstract

This article examines the theoretical size of a sunshade that could be employed to combat the heating effects of climate change. It is found that a change in emissivity of as little as 0.06 could result in a global mean temperature change of around 4 K. To counteract this temperature change, a sunshade of area 7.45x10¹² m² placed at the L₁ point would be required.
